Yes it is possible to do this. The first step is determining whether your logic board supports this. Many disable the integrated video when a video card is added. On some logic boards it is possible to enable both through a setting in the BIOS or UEFI, but not in all cases. If use of both can be enabled, then all you should need to do is attach your monitor to the video port on the logic board for the integrated video from the Intel CPU, and install drivers for both Intel video and the nVidia card. The folding client will not attempt to use the iGPU as it is not supported for folding anyways.

I successfully run Virtu D-mode on my system with a Z87 motherboard; the Z77 system doesn't fully recognize it, even though the drivers seem to load.

I did a few tests when my system was new and found a slight increase in Folding performance with Virtu enabled. I don't know what processes make use of the Intel onboard GPU, but it apparently does a little work...

The integrated GPUs are fine to drive a monitor provided you can follow the procedures noted above.

Though you didn't ask, I'll add a bit of off-topic information related to your question.

Integrated GPUs, whether from Intel or AMD, produce a munch lower number of GFLOPS than almost any discrete GPU. Therefore they would fold MUCH slower if you did actually try to do so. Recent integrated GPUs from AMD can accept the regular AMD drivers, and technically speaking, they could fold, but they're so slow that they generally won't meet FAH's deadlines. FAH does not support the Intel HD drivers for folding although it might be possible on the latest models. Nevertheleess, they'd also fail to meet the deadlines so there has been no reason for FAH to support them as a folding device.

I have previously tried what you suggested but it was not as easy as I first thought.

I will try again at some point, and post back as to whether it works or not.

Thanks again Joe_H for your response.

Jerry.

Did you notice that that link is about Linux, not Windows? For Windows, it is exactly as easy as Joe_H says. Just set the BIOS to initialise the on-board graphics (IGP rather than PEG) and that's it. I have an ancient B75 motherboard which has the monitor connected to the on-board DVI and is folding on a GTX 1050 with no monitor attached.

Using Virtu D-mode ("Discrete"), your monitor cable is connected to the add-in GPU, and that primarily drives the monitor.

If you want the integrated GPU to primarily drive the monitor, you have to set your BIOS to Virtu I-mode ("Integrated"), and connect the monitor cable to the motherboard video output. Note: I have not tried GPU Folding in I-mode, so I don't know the effects. However, if the add-in card is detected by the OS, F@HClient should also detect and be able to use it.

On subtle gotcha is the OpenCL limitation. OpenCL is needed for whatever GPU you want to use for FAH.

It would be nice to have your iGPU render your screen and your videos, leaving the dGPU exclusively for FAH, but that would require all FAHCores to use CUDA. Most NV cores use OpenCL and you'd still have a problem with AMD GPUs which only use OpenCL.

For Windows, it's trivial - AMD or Intel iGPU doesn't matter.This is one of the VERY FEW things Windows does noticeably better than LINUX does.

On Linux, you have to install the drivers for the iGPU first, then manually install the NVidia drivers using the "--no-open-glfiles" option, and you generally end up having to manually edit your xorg.conf to add the card entries, screen entries, and "dummy" monitor entries for each card (along with coolbits to the applicable spots to enable fan control etc).

It's a lovely thing once you get it working the first time - then you can usually "clone" the setup with at most changing the PCI assignments in xorg.conf for each GPU and the iGPU if needed.

AMD iGPUs do nicely on some BOINC projects like Moo Wrapper or Yoyo, running at the same time as your CPU is keeping your Folding GPUs humming away. Intel iGPUs are ... meh, Intel Graphics has never been competative with AMD/ATI or Nvidia - but will still save you some GPU cycles running the desktop on the IGU instead of one of your folding GPUs.

For us to help, you need to post the log showing the problem. (See the signature block of this post.)

I'm not registered at linuxmint.com so I can't see what's there. I hope they can solve it, but there's important information in the preamble to FAH's log ... which also can be obtained with FAHBench as well as GPU-Z. Do both graphics systems have driver support for OpenCL?

Per the notes in the sig of my previous post, we need the first couple of pages of the log. (Your screenshot shows most of that.)

Looking at the screenshot, it appears you're running LInux, that you have some version of drivers which provide support for CUDA but there's no mention of support for OpenCL. FAH is seeing a single CUDA GPU ... a GTX 1060 ... and no alternate GPU. What does something like CPU-Z say about OpenCL and about the alternate GPU?

What happens if you plug a monitor into the iGPU?

This doesn't really look like an issue that's specific to FAH but rather with the Linux drivers.
